Abstract
The utility model discloses a mechanical and electric speed reducer for an elevator door, being composed of an electric motor, a machine base, a housing and a push rod type speed reducer which is directly connected with the output shaft of the electric motor. The principle of speed changing transmission bearing is adopted, so that the output shaft of the electric motor and the output shaft of the speed reducer are on the same one axis. Accordingly, the utility model has the advantages of compact conformation, convenient installation, high mechanical efficiency and low running noise, and can be used on the switching mechanism of the single-opening door, middle-opening door and folding door of various elevators.
Description
The utility model relates to mechanical variable speed drive, relates in particular to the electronic speed reduction gearing of using on the elevator door-motor.
Along with the raising of people's living standard, skyscraper constantly occurs, and the demand of elevator is constantly increased.Simultaneously safe, reliable, the speed and the quietness of elevator are had higher requirement.And to the elevator door-motor electric reducer as auxiliary equipment also proposed efficiently, reliable, peace and quiet and the little requirement of volume.Existing elevator door-motor electric reducer generally is to adopt the multi-stage, belt speed reduction gearing, also has to adopt traditional gear reduction box.These speed reduction gearings all have volume big, the shortcoming that the reverse speedup driving opening of output shaft kinetic moment is big, noise is big.Multi-stage, belt type of drive particularly, structure is numerous and diverse, bulky, need often maintenance, efficient is low, can not pull open elevator door with hand easily in extraordinary circumstances, in fact do not met the requirement of current manufacturing industry of the lift.
The purpose of this utility model provides a kind of elevator door-motor electric reducer, has that noise is low, volume is little, a compact conformation, easy to install, characteristics that efficient is high.
The purpose of this utility model is achieved in that the elevator door-motor electric reducer, and it includes electrical motor, support, shell, connects a push-down reductor on the output shaft of electrical motor.Said reductor be have eccentric bushing, with eccentric bushing bonded assembly bearing, roller along the bearing radial array, said roller is placed in outside race, with these rollers to drive link should be arranged, drive link is installed in the groove of output shaft of trough of belt, and be connected with an internally toothed annulus by roller, output shaft is by bearing and shell relative fixed and stretch out outside the shell.
The utility model will be further described below in conjunction with accompanying drawing.Accompanying drawing is a structural representation of the present utility model.Electrical motor (1) preferably adopts permanent magnet direct current motor, eccentric bushing (2) is installed on its output shaft, power is delivered to eccentric bushing (2) by electrical motor (1), eccentric bushing is equipped with bearing on (2), roller is radially laid in the outer ring of bearing, with these rollers to drive link (3) should be arranged, because the eccentric action of eccentric bushing (2), drive link (3) is pushed, drive link (3) arrives transmission of power on the internal tooth (4) by another group roller, because the antagonistic force of internally toothed annulus (4) curved surface makes drive link (3) around the complete machine rotational, and drive link (3) is to be loaded in the groove of output shaft (5), rotates so drive output shaft (5).Thereby realized the purpose of takeoff output and deceleration.Go up suffered bigger diametral load in order to adapt to output shaft (5), therefore between output shaft (5) and shell, preferably select the higher needle bearing of precision for use.
The utility model adopts the principle of variable speed transmission bearing, the output shaft that makes the output shaft of electrical motor and reductor is on same axis, compact conformation, easy to install, the mechanical efficiency height, noise is low, the output shaft staring torque is little, and long service life operates steadily, can be applicable to the single open-door of elevator, passenger-goods lift and the sample of all size, in open the door and fold the door switching mechanism on.
Claims (3)
1, elevator door-motor electric reducer, it includes electrical motor, support, shell, it is characterized in that on the output shaft of said electrical motor the push-down reductor being installed.
2, elevator door-motor according to claim 1, it is characterized in that said push-down reductor is by eccentric bushing, is installed in the bearing on the eccentric bushing, roller along the bearing radial array, with the cooresponding drive link of roller, the output shaft of the trough of belt of drive link is installed,, output shaft and the relatively-stationary bearing of shell is constituted by another group roller and drive link bonded assembly internally toothed annulus, said roller is the outer ring of laying bearing for one group, and another group contacts with the curved surface of internally toothed annulus.
3, elevator door-motor electric reducer according to claim 2 is characterized in that said output shaft and the most handy needle bearing of the relatively-stationary bearing of shell of making.
